--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Heh, interesting set of events ;)
Now it is interesting how much we desire to perform the tail-merging - we
_could_
change the alias sets of loads (and stores...) to a "common" one (either if
they
are "equal" or just zero otherwise). Depends on how much we like this kind
of pessimization.
Same for the RTL bits of course.
Btw, I still see the conditional execution after RTL expansion, just
cfglayout mode doesn't have unconditonal gotos for the edges.
